1. In a wireless communication system, a method for determining a code phase, the method comprising:

  • generating a first auto correlation function (ACF) within the mobile station, the first ACF being associated with correlation samples over a range of code phases corresponding to a line-of-sight signal;

    generating a second ACF within the mobile station based on measured correlation samples over a range of code phases;

    comparing the first ACF to the second ACF to generate a code phase offset and a weight factor; and

    applying the weight factor to the code phase when combining the code phase with a second code phase from another transmitter.
